Detail Information

characteristic

Pigment Red 81 Description

Advantage:

A pure clean bluish red that matches the magenta hue used in four-color overprint printing inks, with high tint color strength. It is mainly used for printing inks and coloring of cultural and educational supplies, but it has low solvent resistance to polar solvents, such as alcohols, ketones and esters or their mixtures, but is relatively stable to aromatic hydrocarbons and paraffins. We have tone and lake two grades for your choice.
